Definitions

  • Such a router is known from DE-GM 74 15 327. It contains a height adjustment device with a hollow spindle attached to the milling basket, which carries an internal thread at its end.
  • the hollow spindle is rotatable and immovably mounted in the milling basket in the axial direction.
  • a turret stop is arranged on the support table of the router, which carries three setscrews on a turret plate. These can alternately be brought into alignment with the hollow spindle.
  • the hollow spindle is screwed onto the threaded pins with its internal thread, and the height of the support table is adjusted by turning the hollow spindle.
  • the disadvantage of this arrangement is that it does not allow a quick change between several, pre-selected milling depths.
  • the turret stop mentioned does not fulfill this function, because the spindle can only be screwed onto one of the grub screws to set the milling depth. If you want to change the grub screw, you have to loosen the screw connection, as a result of which the milling depth setting is lost.
  • the turret stop equipped with grub screws of different lengths is only used in the known arrangement to avoid very long screw strokes of the spindle when adjusting the height. In contrast, it is not possible to preset several milling depths and quickly between these milling to switch depths.
  • the brochure "Das Milling" from Elu Eugen Lutz KG shows a hand router with a turret depth stop arranged on the support table. This carries three stop bodies in the form of set screws on a turret plate, which can be screwed into sleeves of the turret plate and locked in place with lock nuts.
  • the milling basket carries a depth limiting pin that can be loosened and tightened using a locking screw and runs onto the adjusting screws to adjust the milling depth.
  • a disadvantage of this arrangement is the low precision of the milling depth setting.
  • a sliding guide is provided for the depth-limiting pin, which does not allow fine adjustment of its height. It is also hardly possible to adjust the set screws of the turret stop in their contact position with the depth limiting pin, since their head is then difficult to access for a screwing tool.
  • the object of the invention is to remedy these disadvantages and to provide a router of the type mentioned, in which the milling depth setting can be carried out more quickly, more conveniently and more precisely, and in particular in which a rapid change between a plurality of preset milling depths is possible.
  • the spindle thus acts as a depth-limiting pin, which can be adjusted by screwing, is brought into a bearing position with the support table without being screwed to it, and can be coupled to the support table in this bearing position.
  • This arrangement allows when coupled up to perform a precise milling depth adjustment using the spindle drive, which is particularly convenient and user-friendly.
  • the connection between the spindle and the support table can be loosened and the turret stop can be used to switch between different milling depth settings without losing the accuracy of the setting.
  • the design according to claim 4 allows the adjusting screws to be adjusted or readjusted while the support table is coupled to the spindle. This ensures a very precise, reproducible height adjustment of the router.
  • the height adjustment device of the router is accessible to the operator in a particularly convenient manner.
  • the drive unit 1 is an electric motor that is supplied with power via a cable 2.
  • the cable 2 opens into a handle 3, by means of which the router is held and guided.
  • a switch 4 is integrated, with which the power supply of the drive unit 1 is switched on and off.
  • There is an electronic speed control of the drive unit 1 so that the cutting speed of the milling cutter can be matched to its diameter and the material.
  • the electronic speed control can be operated by a further rotary knob 80 or the same switch 4 on the front handle knob, without the handle 3 having to be released.
  • a pneumatically operated drive unit can also be used.
  • the upper housing part 5 of the drive unit is rounded in such a way that it can be gripped around and lies well in the hand.
  • 1 shows the oval basic shape of the upper housing part 5
  • FIG. 3 shows its approximately elliptical cross section.
  • the drive unit 1 is carried by a milling basket 6, which is preferably detachably connected to the drive unit.
  • the milling basket 6 is a profile body with a rounded front part 7, a base plate 8 and a protruding back 9.
  • the drive unit 1 stands on the base plate 8 and is held in a form-fitting manner between the front part 7 and the back 9, with a centering (not shown further) is provided; for this purpose the back 9 is provided with an upwardly open U-recess through which the handle 3 projects.
  • An opening is provided in the base plate 8 of the milling basket 6 through which a shaft 11, which is rotated by the drive assembly 1, projects.
  • a cutter 12 can be fixed on the shaft 11, and by means of a nut 13 which can be screwed onto threaded pieces at the end of the shaft 11 and on the shaft 14 of the milling cutter 12.
  • the shaft 11 is advantageously blocked.
  • a shaft locking pin 81 can be used for this.
  • the shaft locking pin is advantageously guided in a holder on the milling basket 6 so that it can be inserted into a bore through the shaft 11.
  • the arrangement of such a shaft locking pin 81 has the advantage that only a single wrench for screwing the cutter 12 is required. You can therefore hold the router with one hand during this operation, while the nut 13 is tightened with the other hand.
  • the support table 17 can be on the guide columns 15; 16 adjust the height in the axial direction of the milling cutter 12 or the shaft 11.
  • the guide columns 15; 16 run in fitting holes that are excluded in the milling basket 6.
  • two guide columns 15 are arranged at approximately the same distance from the milling cutter 12; 16 provided, of which the first 15 lies in a longitudinal center plane of the router.
  • the second guide column 16, on the other hand, is extended laterally from the longitudinal center plane. If you think of a circle around the center of the shaft 11 or the milling cutter 12, the angular distance between the guide columns 15; 16 according to the invention about 115 ° - 140 0 ..
  • the fitting bore for the first guide post 15 is in the rounded front piece 7 and the fitting hole for the second guide column 16 in the back 9 of the milling basket 6 are provided.
  • the guide columns 15; 16 dimensioned differently in the illustrated embodiment.
  • the second guide column 16 lying outside the longitudinal center plane of the router is designed to be comparatively solid, so that it essentially supports the support table 17.
  • the first guide column 15, on the other hand, has a smaller diameter; it essentially ensures that the support table 17 is guided in parallel and has a stabilizing effect.
  • at least one guide column 16 contains a spring element, by means of which the support table 17 is pressed away from the milling basket 6. In the exemplary embodiment shown, this is the second, massive guide column 16.
  • Fig. 2 shows that the back of the milling basket 6 is extended upwards in the region of this fitting bore in order to create space for receiving the compression spring.
  • the support table 17 can be locked in certain height positions relative to the milling basket 6.
  • a locking screw 19 is provided, which can be turned by means of a clamping knob 20 and works against the first guide column 15. By tightening the locking screw 19, the movement of the guide column 15 is blocked in the associated fitting bore and the height adjustment is thus fixed. This determines the milling depth of the milling cutter 12; it can be varied continuously.
  • the support table 17 has an opening 21 through which the cutter 12 can be passed.
  • the distance between the support table 17 and the milling basket 6 is now set so that the milling cutter 12 protrudes beyond the support level 22 of the support table by the desired amount; this amount corresponds to the milling depth.
  • the locking screw 19 is loosened and the support table 17 with the guide columns 15, 16 inserted into the associated fitting holes by the desired amount, the force of the compression spring having to be overcome. Then the locking screw 19 is tightened again.
  • a height adjustment device 23 is provided which acts between the milling basket 6 and the support table 17.
  • the height adjustment device 23 is disengaged approximately symmetrically to the second guide column 16 from the longitudinal center plane of the router and arranged in its area opposite the second guide column 16. It has a spindle guide 24 which is firmly connected to the milling basket 6. As can be seen in particular from FIG. 3, the spindle guide is molded onto the back 9 of the milling basket, seen from the second guide column 16 beyond the U-recess which contains the handle 3 of the router. At this point it should be noted that the locking knob 20 of the locking screw 19, like the handle 3, lies in the longitudinal center plane of the router; the clamping knob 20 can therefore advantageously also serve as a second handle when the router is guided with both hands. Referring again to Fig.
  • a spindle 25 is mounted in the spindle guide 24, which can be axially displaced therein by turning an adjusting wheel 26.
  • the adjusting wheel 26 is in turn rotatable in the spindle guide 24, but is held immovably in the axial direction; it is screwed onto the spindle 25, which thus executes an axial longitudinal movement corresponding to its thread pitch when the adjusting wheel 26 rotates. This movement takes place parallel to the guide columns 15; 16, ie in the stroke direction of the support table 17th
  • the support table 17 has at least one stop bolt 27 for this purpose, which lies opposite the spindle 25, so that when the support table 17 is adjusted in height, the end of the spindle touches the stop bolt 27.
  • the stop pin 27 limits the lifting height of the support table 17; Because of this stop action, it is advantageous to attach the stop pin 27 in turn to the support table 17 in a height-adjustable manner.
  • the stop bolts 27 have the shape of set screws that can be screwed into suitable sleeves 28.
  • the stop bolts 27 are part of a turret stop located on the support table 17. As can be seen from FIGS. 1 and 3, three stop bolts 27 are provided which are carried by a turret plate 29.
  • the turret plate 29 has a circular shape; it is rotatably mounted on the support table 17 and adjustable between step-by-step locking positions.
  • the sleeves 28 are arranged offset by the same angle for the set screws, which serve as stop bolts 27; the arrangement is chosen so that in the locking positions of the turret plate 29 one of the stop bolts 27 is aligned with the spindle 25.
  • the stop bolts 27 project from the turret plate 29 at different heights. Each of these height values corresponds to a certain milling depth, which is set by moving the associated stop bolt 27 into alignment with the spindle 25 and then with their end in plant.
  • the turret stop according to the invention thus ensures that milling depths can be repeated in three different stages; these can be adjusted relative to one another by changing the screw-in depth of the set screws serving as stop bolts 27.
  • a fine adjustment and absolute adjustment of the milling depth is carried out by means of the spindle 25, which can be coupled to the stop bolt 27 for this purpose.
  • the spindle 25 carries a pendulum attachment 30 at its end.
  • the pendulum attachment 30 is arranged on a hanger 31 which is pulled onto the spindle 25 and projects laterally therefrom.
  • the protruding part of the hanger 31 contains a bolt about which the pendulum projection 30 is pivotable; the swivel axis runs parallel to the spindle axis, but does not coincide with it. As shown in FIG.
  • the pendulum projection 30 has a claw 32 with a surface rising along an inclined plane, which is suitable for gripping under the head 33 of a stop bolt 27 which is brought into contact with the end of the spindle 25.
  • the pendulum approach is first pivoted so far that the claw 32 lies outside the path of movement of the head 33; as soon as the desired stop position is established, the pendulum projection 30 is then pivoted back so that the claw 32 holds the head 33.
  • a jacket section 34 of the pendulum attachment 30 is provided with grooves 35.
  • the jacket section 34 has a circular cylindrical shape and runs on a correspondingly rounded surface 36 of the hanger 31; the pivot axis of the pendulum projection 30 lies in the center of curvature of this rounding and thus protrudes laterally with respect to the spindle axis.
  • the spindle 25 is hollow, so that a tool can be passed through from above, by means of which the set screws serving as stop bolts 27 can be screwed into the associated sleeves.
  • a scale carrier 37 is used to measure the milling depth, which, according to the invention, also limits the maximum adjustable distance between the milling basket 6 and the support table 17 as an end stop.
  • the scale carrier 37 allows a determination of the distance between the milling head 6 and the support table 17, which is a measure of the milling depth.
  • One end of the scale support 37 can be firmly connected to the support table 17, for. B. screw by means of an angled tab 38 (see. Fig. 2).
  • the other end 39 of the scale carrier 37 runs loosely in a housing opening of the milling head 6. For the abovementioned stop action of the scale carrier 37, this end 39 is also angled Provide tab that can be swung into the housing opening.
  • this hooking is first carried out and then the fixed connection of the scale carrier 37 to the support table 17 is established. If the support table 17 is then extended relative to the milling basket 6, the pivoted-in tab at the end of its path reaches the bottom of the housing bore, through which it does not fit in a linear movement. It reaches an end position in which the support table 17 is locked against further extension.
  • the arrangement according to the invention of a scale carrier which can be pivoted into a housing opening therefore has the advantage on the one hand of serving as a stop in a simple manner; furthermore, such a scale carrier 37 is optimally protected against damage.
  • An arrangement in the front piece 7 of the milling basket 6 is preferred, where the scale support 37 in no way disturbs the view of the milling cutter 12 and is also clearly and legibly readable.
  • the router according to the invention can be provided with fastening means for a parallel stop 64 and similar accessories.
  • the parallel stop 64 shown in FIG. 3 is held on two round rods 65. At a distance from these round bars 65, two longitudinal grooves are recessed on the surface of the support table 17, into which the round bars 65 can be inserted.
  • the longitudinal grooves 66 are bridged at least at one point by webs 67, in which set screws 68 can be screwed in the direction of the round rods 65. By means of these set screws, the round bars 65 are locked in the desired insertion depth, whereby a defined distance between the parallel stop 64 and the router is established.
  • the guide columns 15, 16, which establish the connection to the milling basket 6, are arranged offset with respect to the first exemplary embodiment. They are located at diagonally opposite corners of the support table 17; 6 and 7 show socket 70 in this regard; 71, which receive the end of the guide columns 15, 16.
  • the fitting holes in the bases 70, 71 are placed on round guide columns 15, 16 of different diameters.
  • the guide columns 15, 16 can be held in the bases 70, 71, for example by snap rings.
  • the support table 17 shown in which special stop bolts 27 can be dispensed with.
  • the side of the support table 17 facing the milling basket 6 then has a bore 72 into which the end of the spindle 25 of the height adjustment device 23 is immersed and can be locked by means of a detent spring 73.
  • the spindle 25 preferably carries at its end a conical head and a circumferential notch arranged after it.
  • the locking spring 73 shown is mounted in the bore 72; it has two expandable lamellae 74, which are semicircularly rounded in the engagement area of the spindle head and are suitable for engaging in the notch of the spindle 25 and thus establishing a coupling between the spindle 25 and the support table 17.
  • a release button 75 is provided to release this locking position.
  • the router according to the invention is ergonomically particularly favorable in several respects. On the various handles lying in the longitudinal center plane of the router possibilities have already been referred.
  • the height adjustment device 23 according to the invention in connection with the compression spring-loaded spacing of the support table 17 enables a fine adjustment of the milling depth without a tensile or compressive force having to be exerted on the support table 17; the force required for its adjustment is rather applied by the spring element in the guide column.
  • the fine adjustment can be made with the thumb while the machine is running without the operator having to release his hand from the handle 3.
  • the speed of the drive unit 1 can be changed and the fine adjustment of the height stop can be carried out without having to let go of an operating handle, and the arrangement according to the invention also ensures flexible, safe milling with a large field of view.
